Unit-Cell Deformation under Discontinuous Deposition of Barium–Strontium Niobate Films

Аннотация

Epitaxial Sr_0.5Ba_0.5Nb₂O₆/MgO thin films with layers of differing thickness (but with identical total thickness) have been prepared by radio-frequency magnetron sputtering with application of discontinuous deposition technology. It is established that a decrease in the layer thickness intensifies the unit-cell deformation, which is retained if the thickness of subsequent layers does not exceed the critical value.
